, CLEVELAND, OHIO. v 1 i FLUSHING-TANK.

To all whom it may concern:-

Be it known that I, FRANKSoHm-ER, citizen of the United States, residingat Cleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful Improvements in F lushing-Tanks, of which thefollowing is a specification.

'My invention relates to an improvement I ber bulbs more commonly used.

In the accompanying drawings, Figure l is a side elevation and verticalsection of the flushing tank embodying my invention, and Fig. 2 is aplan view and horizontal section of Fig. 1.

The tank 2 may be of any suitable construction adapted to hold apredetermined amount of water, the level or height of which is fixed bya valve 3 and float 4. V This valve is mounted to slide upon the upperend of'a supply pipe 5 which extends upwardly into the bottom of thetank, and the float 4: is pivotally mounted at the upper end of ascrew-threaded stem 6 carried by a lug 7 on the supply pipe. Adjustmentof the screw stem to raise or lower the pivot for the float determinesthe level of the water in the tank, and this level is fixed at a slightdistance below the bend 8 in an inverted U-shaped siphon member 9 havinga flexible or bendable portion 10, shown in Fig. 1 as a separate rubbertube or pipe reinforced or strengthened internally by a coiled spring11. The intake end 12 of this siphon mem- 'ber may be of metal with itsextremity 13 bent to project substantially parallel with the verticalextension of the outlet pipe 14 which is secured to or made integral.with an outlet fitting or member 15 fastened by a nut 16 at the bottomof the tank. The intake and bendable portions of the siphon member arepreferably inclined or set at an angle to promote an instant flow andcomplete submersion of the upper bend 8'upon imparting a pull or pushthereto through the r medium of an operating device of any suitablecharacter. As shown, a lever 18 is used Specification of Letters Patent.

which is operatedby a handle 19 placed upon theoutside of the tank andwhen-the siphon member is flexed and carried beneath the level of thewater, a flow of water is established through the siphon .member and thetank siphoned of its contents. As soon, as the water level drops to theopen extremity l3 and air is admitted the siphoningaction is broken andcannot be again established unless water is again admitted into the tankand maintained at the original higher level.

Admission of water into the tankis automatically controlled by valve 3and float' l. Thus, when the float drops valve 3 israi'sed sufiicientlyfrom the upper end of supply pipe 5 to admit water into the tank throughthe lateral passage 20 and a downwardlyextending pipe 21, and the inflowof water into the tank will continue until the float l rises and setsvalve 3 solidly against the upper 'end of supply pipe 5.

PatentedliIa1'..3(),1920. Application filed January 29,1919; Serial No,273,853. i i I I A by-pass pipe 22 is also provided to deliver waterfrom the supply pipe 3 directly to a branch stand-pipe '23 whichconnects with the outlet fitting 15 for the tank, but the flow throughthis by-pass 2 is shut oif when the tank isfull and valve 3 is seatedand closed. Thepurpose of this auxiliary flow of water to the outlet forthe tank is to supply the closet bowl with suiiicient water to fill thebowl to a predetermined level after flushing operations. i

What I claim is:

1 In flushing tanks, a tank and an outlet fitting extending into thetank and .bent. laterally at its inner end, a flexible tube affixed tosaid fitting and projected in con-. tlnuatlon of the bend therein, acoiled wire spring engaged with the walls of saidtube and adaptedtosustain the same in normal posltion, a siphon tube having a U-shapedextremity secured to the upper end of said flexible tube and providedwith a straight body portion lying relatively over the back of saidflexible'tube and parallel therewith and having its intake end bentinwardly toward the said outlet fitting and the mouth thereof relativelynear'the bottomf-of' the tank, and means to bring said tubes into siphonstarting position. i

2. In flushing tanks, a rlgidfitting'in the p bottom of the tank havinga laterally curved end, a straight rubber tube secured to said end and asustaining spring coil therewith,'

a siphoning tube having one end bent to U-shape and fixed upon saidrubber tube and said siphoning tube havinga straight body disposedlengthwise over and next to the said rubber tube and having'its lowerend partially overlapping said rubber tube and bent inward arallel'thereto.

3. In fluslung tanks, a tank having a tubular fitting set upright in thebottom thereof nd havi g its inner end turned to an inclined position, astraight flexible tube pro jecting in prolongation of said bent end andsecured thereto and a coiled ire spring in said flexible tube adaptedtosustainthe tube in working position, a siphoning tube having 3 2urshaped end fixed on said flexible tube; and having its body inclinedand its intake; end bent toward said fitting, and means to? actuate saidtubes and cause them tosiplion. l20 Y Signed Cleveland, in the county ofCuyahoga, and State of Ohio, this 8th day of January, 1919:. s V
